New Automatic Technology for Space PCB Assembly

PCB Assembly of Flight Electronics is the traditional & core activity having been developed since 1994. The CSRC cleanroom located in Kromeriz was the very first ESA qualified facility for manual space electronics PCB assembly in the Czech Republic.

 

To increase the manufacturing power and capabilities BD SENSORS built-up the very first space qualified automatic PCB assembly line in the Czech Republic located in Buchlovice.

 

The automatic assembly line is installed in cleanroom ISO class 8. The line consists of both complementary machine and additional hand soldering technology. For the additional hand soldering activities minimum of 4 new workplaces are included. In addition, there are workplaces for all activities which are necessary for completion of the Flight Units including mechanical integration, gluing, harness, crimping, electrical testing, etc.

 

The complete production line for ECSS-qualified electronics assembly covers the following process:

  • Parts preparation (cutting/bending, degolding, pretinning)
  • Pick&place including electrical check
  • Vacuum vapor phase soldering
  • Gluings
  • Manual solderings (SMT, THT)
  • Cabelings
  • Visual inspection
  • Logistics

 

Machine soldering is based on:

  • Vapour phase technology with vacuum unit ASSCON VP 800.
  • Solder paste will be applied through stencils on semi-automatic printer Fritch SD903
  • Semi-automatic pick and place machine Fritch SD902pro

 

Additional hand soldering workplaces are equipped:

  • JBC nitrogen soldering unit for complicated soldering activities
  • Various soldering tools for different soldering activities
  • Infrared preheating for soldering thermal mass areas on PCB
  • Set of hand tools for all manual activities (tweezers, stripping tools, pliers, etc.)

 

 

Assembly line consists of the following workplaces:

  • Place for PCB inspection
  • Place for glue mixing, degassing and application by dispenser
  • Ovens for PCB baking, glue curing, components demoisturization
  • Separated place for silicones application
  • Place for components degolding and pretinnig
  • Place for components and PCB cleaning
